Day11-pygame应用

1.pygame事件

• QUIT:关闭按钮被点击事件
  MOUSEBUTTONDOWN:鼠标按下

  • MOUSEBUTTONUP：鼠标弹起

  • MOUSEMOTION：鼠标移动

  • 关心鼠标事件产生的位置

  • pos属性，获取鼠标事件产生的位置

  • KEYDOWN：键盘按键被按下

  • KEYUP：键盘按钮弹起
    关心键盘事件产生的位置
    *key属性，获取被按的按键对应的Unicode编码
    *chr,将Unicode转换为字符

import pygame
if __name__ == '__main__':
    pygame.init()
    screen=pygame.display.set_mode((600,400))
    screen.fill((255,255,255))
    # screen.blit()
    # 设置游戏事件
    pygame.display.set_caption('游戏事件')
    pygame.display.flip()
while True:
        #每次循环检查事件
        for event in pygame.event.get():
            #不同类型的事件对应的type值不一样
            # pos属性，获取鼠标事件产生的位置
            if event.type==pygame.QUIT:
                exit()
            if event.type==pygame.MOUSEBUTTONDOWN:
                print('鼠标按下',event.pos)
            if event.type==pygame.MOUSEBUTTONUP:
                print('鼠标弹起',event.pos)
            if event.type==pygame.MOUSEMOTION:
                print('鼠标移动',event.pos)
            #键盘相关事件
            if event.type==pygame.KEYDOWN:
                print('键盘按键被按下',chr(event.key))
            if event.type==pygame.KEYUP:
                print('键盘按钮弹起',chr(event.key))

2.pygame的应用

import pygame
from random import randint
# 画一个按钮
def draw_button(screen,btn_color,title_color):
    # 画个鼠标
    '''矩形框'''
    pygame.draw.rect(screen, btn_color, (100, 100, 100, 60))
    '''文字'''
    font = pygame.font.SysFont('Times', 30)
    title = font.render('clicke', True, title_color)
    screen.blit(title, (120, 110))
# 写一个函数，判断指定的点是否在指定的矩形范围中
def is_in_rect(point,rect):
    x,y=point
    rx,ry,rw,rh=rect
    if (rx<=x<=rx+rw) and (ry<=y<=ry+rh):
        return True
    return False
def draw_ball(screen,pos):
    pygame.draw.circle(screen, rand_color(), event.pos, randint(10, 20))
    # 只要屏幕上的内容有更新，都需要调用下面的两个方法
    pygame.display.update()
    # pygame.display.flip()
def rand_color():
    return randint(0,255),randint(0,255),randint(0,255)
if __name__ == '__main__':
    pygame.init()
    screen=pygame.display.set_mode((600,400))
    screen.fill((255,255,255))
    pygame.display.set_caption('鼠标事件')
    draw_button(screen, (0, 255, 0), (255, 0, 0))
    pygame.display.flip()
    while True:
        for event in pygame.event.get():
            if event.type==pygame.QUIT:
                exit()
            if event.type==pygame.MOUSEBUTTONDOWN:
                # draw_ball(screen,event.pos)
                if is_in_rect(event.pos,(100,100,100,60)):
                    draw_button(screen, (0, 0,255 ), (255, 0, 0))
                    pygame.display.update()
                    print('点中按钮')
            if event.type==pygame.MOUSEBUTTONUP:
                draw_button(screen, (0, 255, 0), (255, 0, 0))
                pygame.display.update()
            if event.type==pygame.MOUSEMOTION:
                screen.fill((255,255,255))
                draw_button(screen, (0, 0, 255), (255, 0, 0))
                draw_ball(screen,event.pos)

结果：

3.pygame应用2

'''
import pygame
def get_image(address,pos):
    images = pygame.image.load('./bomb.png')
    x, y = images.get_size()
    x1, y1 = event.pos
    address.blit(images, (x1-int(x/2),y1-int(y/2)))
    return images
def is_in_image(images,pos,num1,num2):
    x,y=images.get_size()
    x1,y1=event.pos
    if (num1<=x1<=x+num1) and (num2

4.动画效果

'''__author__==fubo'''

'''
动画原理：不断的刷新界面上的内容(一帧一帧的画)
'''
import pygame
from random import randint
def static(address):
    font=pygame.font.SysFont('Times',40)
    title=font.render('welcome',True,(255,0,0))
    screen.blit(title,(50,50))
def animation_title(address):
    font = pygame.font.SysFont('Times', 40)
    title = font.render('welcome', True, (randint(0,255), randint(0,255), randint(0,255)))
    screen.blit(title, (100, 100))
if __name__ == '__main__':
    pygame.init()
    screen=pygame.display.set_mode((600,400))
    screen.fill((255,255,255))
    static(screen)
    pygame.display.flip()
    while True:
        for event in pygame.event.get():
            if event.type==pygame.QUIT:
                exit()
        # 不断改变字体的颜色
        # 程序执行到这个位置，cpu休息一段时间再执行后面的代码(程序堵塞)
        # 单位：毫秒(1000ms=1s)
        pygame.time.delay(160)
        # 内容清空
        screen.fill((255,255,255))
        static(screen)
        animation_title(screen)
        # pygame.time.wait(1000)
        # 内容展示
        pygame.display.update()

结果：
